We believe that the next evolutionary step in supporting wide-area application and services delivery to customers is a network framework that provides for collocation of applications and services at distinct sites in the network, an interconnection between these sites that is performance optimized for these applications, and value-added services for applications. We use the term IsoWAN to descr...

A system for mobile office and entertainment applications was developed. The input modalities include touch screen and automatic speech recognition, the output modalities screen output and speech synthesis. Services comprise an e-mail reading and responding application, a configurable news feed reader and, as entertainment, a license plate information application. Android Technology with web se...

In Service-Oriented Architectures (SOA), service descriptions are fundamental elements. In order to automatically execute SOA tasks, such as services discovery, it is necessary to capture and process the semantics of services. We review several Semantic Web Services frameworks that intend to bring semantics to Web Services. This chapter depicts some ideas from SOA and Semantic Web services and ...

Standard application packages are used to improve business processes and to reduce costs for information systems. Standard application packages in the form of ERP systems (Enterprise Resource Planning systems) are common among private sector organizations. Public sector organizations use standard application packages developed for specific areas of government operations. Today, the design, use ...

This paper describes how WSPeer, a framework for deploying and invoking Web services, allows application code to host and invoke Web services. We show how the mechanisms used by WSPeer shield applications from implementation changes and enable applications to easily expose elements of themselves as Web services. The mechanisms described differ from usual Web service deployment scenarios in whic...

RÉSUMÉ. Cet article présente une approche centrée exigences pour la composition de services web qui permet : (i) la modélisation des exigences des utilisateurs avec le formalisme la Carte et la spécification des services requis avec un modèle intentionnel de services (MIS) ; (ii) la découverte des services web pertinents en interrogeant le moteur de recherche de services Service-Finder ; (iii) ...

Application domains such as multimedia, databases, and parallel computing, require operating system services with high performance and high functionality. Existing operating systems provide xed interfaces and implementations to system services and resources. This makes them inappropriate for applications whose resource demands and usage patterns are poorly matched by the services provided. The ...

 To use services transparently in a distributed environment, the Utility Grids develop a cyber-infrastructure. The parameters of the Quality of Service such as the allocation-cost and makespan have to be dealt with in order to schedule workflow application tasks in the Utility Grids. Optimization of both target parameters above is a challenge in a distributed environment and may conflict one an...

By design, a federated “system of systems” application offers limited control over the components and services that it is built upon. However, as the application evolves, there will be changes required to the components and services that comprise the application. As these services are likely to support multiple federated applications, not all will evolve in the same manner. It is essential to l...
